Aliasing with as

Renaming imports and exception variables.

python
# Import aliasing
import math as m
print(m.pi)
print(m.sqrt(25))

from datetime import datetime as dt
print(dt.now().year)

# Exception aliasing
try:
    result = 10 / 0
except ZeroDivisionError as e:
    print(f"Error: {e}")

# Context manager aliasing
class Resource:
    def __enter__(self):
        return {"status": "open"}
    def __exit__(self, *args):
        pass

with Resource() as r:
    print(f"Resource: {r}")

'as' creates an alias — a new name for an imported module, caught exception, or context manager result. It makes code cleaner without extra assignment lines.
